Description
Technical field
The present invention relates to a kind of methods that carbon black decontamination technology more particularly to a kind of carbon black take off PAHs.
Background technology
It is light, the loose and superfine black powder of amorphous carbon that carbon black, which is a kind of main component, and surface area is very big, range
It is organic matter from 10-3000m2/g（Natural gas, heavy oil, fuel oil etc.）Under conditions of lack of air through imperfect combustion or
Product obtained by being thermally decomposed（With larger adhesiveness）.The application field of carbon black is very extensive, can make black dyes, be used for
Chinese ink, ink, paint etc. are manufactured, is also used for cooking the reinforcing agent of rubber, has important role in industrial circle.Traditionally,
In manufacturing technologies of carbon black flow, air and fuel burn in reacting furnace, and raw material sprays into after atomization in burned flame, warp
High temperature pyrolysis generates carbon black.Carbon black, which is suspended in combustion gas, forms flue gas.Flue gas sent after chilling air preheater, oil preheater into
One step cools down, and the flue gas after air preheater cools down can be sent into bag hose after the cooling of postorder heat exchanger again, the charcoal isolated
Black be sent in comminutor is granulated, then dry in drying machine.The a large amount of energy can be consumed in carbon black process, such as just
Stage beginning will be filled with 1000 DEG C of preheating gas, just need to have reached nearly 2000 DEG C in the temperature of high-temperature pyrolysis stage, with
It also needs to that carbon black smoke cool to the carbon black powder mask work that could carry out next step portion after 900 DEG C or so afterwards.It is whole
A process is all in largely consumption energy, waste energy.
Polycyclic aromatic hydrocarbon (PAHs) refers to a kind of organic compound with two or more phenyl ring.Polycyclic aromatic hydrocarbon is point
Hydrocarbon, including naphthalene, anthracene, phenanthrene, pyrene containing more than two phenyl ring in son etc. more than 150 plants compound.Full name in English is
Polycyclic aromatic hydrocarbon, abbreviation PAHs.Some polycyclic aromatic hydrocarbons also contain nitrogen, sulphur and pentamethylene, common
Polycyclic aromatic hydrocarbon have carcinogenesis polycyclic aromatic hydrocarbon be mostly four to six rings fused ring compound.International cancer research center（IARC）
（1976）The 94 kinds of compounds carcinogenic to experimental animal listed, wherein 15 kinds belong to polycyclic aromatic hydrocarbon.Polycyclic aromatic hydrocarbon (PAHs)
It is a kind of very serious pollutant.
In the production process of carbon black, the inevasible generation of polycyclic aromatic hydrocarbon (PAHs) meeting, while again because of carbon black itself
With adhesiveness, PAHs can be attached on carbon black, the PAHs that general physics cleaning filter method can not be on fully erased carbon black,
So that still having pollutant on carbon black products, do not simply fail to through external environmental protection verification, it can also be in actual production to worker
It damages.
Invention content
The present invention is directed to deficiency in the prior art, provides a kind of manufacturing method of energy conservation and environmental protection carbon black, can be effective
Removal is attached to polycyclic aromatic hydrocarbon (PAHs) and other impurities on carbon black so that carbon black feed stock asepsis environment-protecting solves carbon black
The problem of distributing polycyclic aromatic hydrocarbon (PAHs) pollution environment in process of production as raw material and endangering workers ' health.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals, a kind of energy conservation and environmental protection carbon black
Manufacturing method, need utilize reaction unit, preheating device and prilling granulator, reaction unit includes reacting furnace, and reacting furnace includes
Burning zone, trunnion, reative cell and cooling section, prilling granulator include carbon black bag hose, Granulation Equipments and drying device, also include with
Under several steps：Step A）：Air and fuel burn in burning zone, and raw material sprays into after atomization from trunnion to be passed through in reative cell
Pintsch process reacts to form carbon black smoke, and carbon black smoke carries out chilling cooling in cooling section, then into traveling in preheating device
One step cools down, and the carbon black smoke after cooling is carbon powder and tail gas by separating and filtering in carbon black bag hose；Step B）：Using wet
Method is granulated, and water is added after entering Granulation Equipments in carbon powder, and with carbon black mass percentages, the water includes 0.1% ~ 5%
Liquid oxidizer obtains carbon black pellet after granulation, the water content of carbon black pellet is 40% ~ 80% at this time；Step C）：Carbon black pellet into
Enter drying device to be dried, drying temperature is between 1000 DEG C ~ 1200 DEG C in drying device, and carbon black pellet adsorbs when dry
Liquid oxidizer to being modified processing to carbon black pellet surface at high temperature, occur with the impurity that is attached on carbon black anti-
It answers；Step D）：After treatment had both obtained qualified carbon black pellet.
In above-mentioned technical proposal, it is preferred that the oxidant is hydrogen peroxide.
In above-mentioned technical proposal, it is preferred that the impurity includes polycyclic aromatic hydrocarbon, nitrogen oxides, oxycarbide.
In above-mentioned technical proposal, it is preferred that with carbon black mass percentages, the water includes 0.5% liquid oxidatively
Agent.
The industrialized production of existing carbon black is mostly feedstock oil high-temperature cracking method, due to feedstock oil purity and original itself
Cause, inevitably incomplete combustion generates polycyclic aromatic hydrocarbon (PAHs) during the Pintsch process of feedstock oil and other are miscellaneous
Matter, part polycyclic aromatic hydrocarbon can be decomposed reduction in remaining preparation process, but carbon black itself has certain adsorptivity, also
Part polycyclic aromatic hydrocarbon and impurity can be attached to the surface of carbon black.Since the polycyclic aromatic hydrocarbon that is attached on carbon black can not be with general
Physical filtering method effectively removes, and then oxidant, the charcoal in carbon black pellet drying process is added in the pelletizing of carbon black stage in the present invention
The polycyclic aromatic hydrocarbon (PAHs) on black surface is decomposed.Since the stability of carbon black itself is strong, temperature can reach when dry
1000 DEG C or more, polycyclic aromatic hydrocarbon (PAHs) and oxidant energy fast reaction at these elevated temperatures, without influencing whether carbon black itself.This
The oxidant of invention is hydrogen peroxide, the pair that hydrogen peroxide generates when reduction reaction occurs at 1000 DEG C or more with polycyclic aromatic hydrocarbon (PAHs)
Product is mainly vapor, carbon dioxide etc., and the drying for not influencing carbon black itself not only is also consistent with exhaust gas component, is easy place
Reason.
Compared with prior art, the present invention can effectively remove the polycyclic aromatic hydrocarbon (PAHs) being attached on carbon black and other
Impurity so that carbon black feed stock asepsis environment-protecting solves carbon black as raw material and distributes polycyclic aromatic hydrocarbon (PAHs) in process of production
The problem of polluting environment and endangering workers ' health.
